Great information. But the problem is that most Banks find it very difficult to teach customers how to protect their information the more. On the other hand it should be the customers responsibility to protect the money they have suffered for.

The first digit tells you what type of business issued your card. The first six numbers identity your bank/issuer specifically. The seventh and following digits identify YOU. The final number checks you typed everything in correctly. You can also check whether any credit card number is valid using the Luhn algorithm. The Luhn algorithm is only in place to check for mistakes when typing your number in online or reading it out over the phone.
